摘　　要：电力系统故障后的电压延迟恢复问题可能导致系统负荷的大量损失,从而威胁系统安全运行。将基于轨迹灵敏度的动态无功规划方法用于抑制电压延迟恢复问题。通过轨迹灵敏度指标确定抑制电压延迟恢复问题的动态无功补偿安装地点,并在所确定的补偿点加装合适容量的静止无功补偿器。最后通过新英格兰39节点系统验证了该方法的有效性。Delayed voltage recovery is becoming a threat to power system security. This paper presents the allocation of dynamic VAR resource to mitigate the delayed voltage recovery （DVR） in power systems. The study is focused on using a trajectory sensitivity index （TSI） to obtain the most effective location of SVC to mitigate the DVR problems. Simulation results of the New England 39-bus system show that the trajectory sensitivity based method is effective for solving the FIDVR problems.
